This invention relates to me extinguishing apparatus. In the industriesdealing with heavy oils and the like both stationary and transportabl'eextinguishing apparatus are used for fight ing fires. The mobileapparatus possess the advantage iover stationary plants that the initialcost in respect of the works to be protected is lower and that they canat any time be applied at different points of the works, for example arefining plant or the like. It is desirable for herent in the designwhich sometimes is too great to allow the extinguishing apparatus beingmoved through doors, or passed under already existinB pipe systems andsteel structures. The mainobject of the present invention is to overcomethese drawbacks for which purpose the apparatus is made transformable atleast to the extent of these fire extinguishing apparatus to have a formwhich renders them quickly applicable so that they give effectiveprotection. They are used principally for tanks having their bases atground level as well as for tanks let into the.

ground (underground tanks) and for refining plants and other works inwhich oils are prepared, but in addition they may be employed inconnection with chemical works. .Having regard to the different uses ofsuch an apparatus, which is required for protecting equally well builtin p the open tanks, underground tanks and furtherwhich is mountedslewably and separately on the proposed to employ a triang ar supportingstructure, consisting of a first, outer pipe section, a

supporting frame adapted to be rigidly connected to the lower end of thesaid pipe section, and a rigid rod structure connecting the upper partof eliminating the undesirable effect of the turning moment for thepurposes of transportation, and

furthermore so as to reduce the overall height of the apparatus in orderto eliminate these diiiiculties. To do this the telescopic pipe sectionsare mounted displaceably in relation to the turntable and the chassis insuch a way that the centre of gravity of the pipes is displaced inrelation to the chassis. Thus, the pipe assembly is no longer rigidlyconnected to the turntable or to the chassis carrying them, nor rigidlyconnected to the supporting frame, rather does the pipe assembly, whichif desired may be provided with lateral journals and adapted to beremoved from its working bearings, rest in a slide guide, which enablesthe pipe assembly, for transporting purposes, to be withdrawn upon thechassis rearwardly if desired into a recess in the counterweightprovided at the rear of the chassis. At the same time the rigidity ofthe triangular, supporting structure is also done away with, and for thepurpose of reducing the overall height during transportation thesupporting frame turntable, or on a part connected to the saidturntable, isswung out of the way so that when the pipe sections arebeing retracted the said supporting frame also carries out a slewingmotion around its axis of rotation, until the upper the supporting frameto the free end of the first pipe section.

Although fairly good results have been obtained with this wholly noveldesign, it has been found to possess however some drawbacks, which areless concerned with the extinguishing action proper, which is entirelysatisfactory than with the mechanical construction per se.

A drawback which constitutes a difliculty has;

size forward. It has also sometimes been found to be a drawback that theaforementioned triangular supporting structure and in particular theframe on the chassis. possesses a height intelescopic pipe sections.

side of this frame comes down to the level of the .pipe sections. Theconstructional arrangement Just outllnedadmits of several specificsolutions, some tending towards the idea of leaving the supporting framerigidly connected with the elevating means for example the screwspindles, and others relating to the practice of disconnecting the rigidrod, and partly making use of the idea of disconnecting from thesupporting frame the elevating means, which are in the form of screwspindles and which for the purpose of being detachably secured can beheld in holders on thesupporting frame by means of nut members, whilstretaining the connection between the supporting frame and the rigid rod.

. Special attention must be paid to the guiding of the ropes forextending and retracting the It is particularly when the extendedsections are in horizontal position that they require supporting ropeshaving their point of attachment at the upper end of the supportingframe and extending thence to the front end of the pipe assembly, inwhich position they are exposed to heavy pulling stresses. Further ropesare required for extending and retracting the telescoping pipe sections.object of the invention is to provide a fire extinguishing apparatuswhich in case of danger can be brought into use quickly, and whichcomprises the lea' possible number of separate parts, and in which therequisite guy ropes and pulling ropes are combined in a suitable manner,while at the same time taking care that the guy ropes are independent ofthe pulling ropes so that the former can carry out their duty ofsecurely holding the pipe assembly in any position. In principle this issolved by connecting the guy ropes which are attached to the supportingframe to the rear end of ,the third pipe section via pulleys provided atthe front end of the second pipe section, and by connecting the frontpipe section to the rear end of the first pipe section via apullingmedium, which is passed through the interior of the pipes to a drum, towhich rotation is to be imparted and which is provided at the rear endof the pipe section, and to a loose pulley acting in the manner oftackle of pulleys. The pin of this loose pulley is connected to the rearend of the second pipesection via a pulley disposed at the front end ofthe first pipe section, if necessary by interposing a further loosepulley acting in the manner of a tackleof pulleys for, each furtheradded slidable pipe section, which is connected to its neighbour bymeans of a pulley disposed at the front end and a rope passed around thesaid pulley. The pulling means which are passed through the interior ofthe pipes is preferably in the form of a chain and in this case the drumat the rear end of the pipe assembly is in the form of a chain wheel. Ifthe two chain wheels for the two draw chains are placed horizontally andeach connected to a wormwheel it is possible by means of a worm actingupon both wormwheels to move both chains forward or backwardsimultaneously.

As extinguishing medium use can be made of foam, smothering gases andthe like. The front pipe section can consist of two or more pipes placedparallel to one another in a bundle, in order to make it possible toconvey the various components appertaining to the extinguishing mediumseparately to the mouthpiece of the pipe assembly, or the various pipesof the bundle can be used for conveying extinguishing media of differingcomposition (air foam, chemical foam and the like), to the mouthpiece ofthe pipe assembly. From an economic point of view it has of advantage inthe case of a small fire which does not require for example largequantities of foam to convey the extinguishing foam only through one ofthese pipes while yet taking full advantage of the extinguishing pipe.In this case each of the separate pipes can be provided with its ownnozzle and the various nozzles can be of differing length. In this formthe pipe assembly offers the further advantage that if one of the pipesin the bundle is damaged, the assembly is not thereby put out of action,the damaged pipe being simply cut out, for example by means of anautomatically acting device working for example on the principle of acheck valve. At the rear end these various pipes in the bundle at thefront are then of course connected to a corre- A further spending numberof hosepipes which are passed through the interior of the pipe assembly.

The fire extinguishing pipe which consists of several telescopicallymounted pipe sections I, 2, 3, is disposed upon a turntable 30, carriedon the chassis 3|, and adapted to be erected, the chassis being fittedwith two, three, or four, preferably rubber-tired wheels 32. Thisturntable carries at the rear a box-like superstructure 33, which can befilled with water or sand and thus act as a counterweight for the fireextinguishing pipe proper. By means of a crank which can be placed onthe pin 27 the turntable with the extinguishing pipe and the box 33 canbe slewed via a gearing not described herein in detail. The fireextinguishing pipe itself is provided at the rear end a triangularsupporting structure consisting of the first pipe section I, thesupporting frame 4 rigidly connected to the rear end of the pipe sectionI, and consisting preferably of two supporting arms connected at the topby means of a cross member, and finally of rigid rods 5, which connectthe free end of the first pipe section I to the upper part of thesupporting frame 4.

Where the first pipe section I is connected to the supporting frame 4this bearer possesses trunnions I I which can be placed in tippingbearings provided at both sides of the turntable 30, in such a way thatthe bearer together with the pipe sections can be slewed and thus alsoraised in these bearings. These tipping bearings I2 for accommodatingthe trunnions II can also be in the form of bearings open at the rear orat if necessary the top, as their only purpose is to take up hearingpressure. The adjusting for height is effected by means of the elevatingmeans attached to the rear end of the chassis, the said means beingdetachably connected to the upper end of the supporting frame 4. Twospindles 6 are preferably used as elevating means. which can be insertedin holders I4 pivotally mounted at the upper end of .the supportingframe 4. The rear ends of these spindles are preferably adapted to bepivotable to a certain extent around a suitable point on thesuperstructure 33 which serves as counterweight, so that they can bemoved through a certain angle in harmony with the turning of thetriangular supporting structure when the extinguishing pipe is beingraised. The spindle drive is actuated by a crank placed on the pin 28.

The arrangement of the holders l4 on the supporting frame 4 can be seen.in Fig. 2. Each holder is provided with a bore through which a bolt canbe passed, or if desired, a shaft passing also through the holder on theopposite side; by means ofa nut I 6 the ho der and at the same time theends of the rigid rod 5 as well as the rear eyelets of the guy ropes Iare pressed against one of the side members of the supporting frame. Thebearing is provided with two bearing surthe same time prevents the pipeassembly from falling of! the chassis.

, In order to enable the supporting frame 4 to be folded down so as toreduce the overall height of the apparatus, the trunnions i I arewithdrawn from the tipping bearings l2 and also pushed back on thechassis or turntable in sliding guides provided for this purpose, sothat the supportingframe 4 together with the spindles 6 which refaceshoulders which form the bearing surface which the push or pull exertedby the spindles 6 upon the holders I4 during the rotation of saidspindles is transmitted to. the supporting frame 4 the bolts which areappropriately dimensioned. By means of a cover 2| hinged on the holderand which can be secured by means of the wing-nut 23 the holder l4 canbe closed at the top, so that the nut member is is secured against anyrotation, displacement or dropping I out.

Figures 4 to 8 illustrate the disconnecting of the arrangement of thepipe sections I, 2, 3 which is displaceable in relation to the chassis3|. If the first pipe section I is as shown in Fig. 4 Provided with abearing foot 22 in the form of a fork, this foot can be connected to thevertical posts of the supporting frame 4 by means of the bolts 9, thesaid bolts meshing in openings provided in the said posts. Theconnection is established either by means of threads on the bolts or thebolts can be placed under the action of a spring which draws the boltsthrough the bolt holes in the foot 22 into the holes in the supportingframe posts. Disconnecting is in this case easily and simply effected bydrawing out the bolts against the spring action, whereby the rearfork-shaped shoulders 22 of the pipe section I is released from thesupporting frame 4.

If for the purpose for example of facilitating transportation of theentire apparatus on the chassis, the telescopically mounted pipes are tobe still further retracted or pushed back on. the chassis so that theircentre of gravity coincides approximately with that of the chassis notonly the aforesaid connecting bolts 9 are as mentioned abovedisconnected thus releasing the fork-shaped shoulders 22 from thesupporting frame 4, but as shown in Fig. 5, also the upper ends of thestays incorporated with the rigid rod 5 are disconnected from the upperend of the supporting frame 4, preferably folded together side by sideand placed flat upon the first'pipe section I. The pipe can then bepushed further back upon the chassis, and to do this the floor of thechassis frame 3| or of the turntable 30 is preferably provided with asliding guide extending rearwardly which enables the pipe to be'pushedback easily and at main connected thereto can be tilted forwardly as,can be seen in Fig. 5. For this purpose the said spindles are of coursepivotally connected at the rear as already mentioned, and the holders l4which receive the nut member H! at the top of the supporting frame postsare also pivotally mounted.

In order to enable the pipe assembly to be pushed back thesuperstructure 33 which is provided at the rear of the chassis foraccommodating the counterweight is provided with a hollow passageextending rearwardly in the centre thereof, so that the pipe assemblycan if desired I be pushed back beyond the rear edge of 'thissuperstructure or of the chassis.

In the embodiment shown only diagrammatically in Figs. 6 and 7 anadditional rigid system of rods 34 has been provided by means of whichthe rear end of the pipesection l is connected to the upper end of thesupporting frame 4, a ring being for example provided at the rear end ofthe said pipe section. This system of rods 34 consisting for example oftwo stays, is slideably' guided in slots 35 provided in; the verticalposts of the supporting frame 4, being at the same time articulated onthe pipe section I.

If after the stays appertaining to the rod 5 have been disconnected fromthe supporting frame 4 as hereinbefore explained, the pipe assembly isto be pushed back, the said pipe assembly is pushed through thesupporting frame 4 which is held in position by the spindles 6, so

that the additional rods 34 together with their connecting members moveupwardly in the slots 35 until they reach the upper edge of the saidslots, moving downwardly again as soon as the pipe assembly has passedthrough the supporting frame, until they again reach the lower edge oftheslots. If now the spindles are rotated via the aforesaid crank pin 28the supporting frame 4 will be folded down rearwardly at the same timeexerting pressure upon the rods 34, so that the pipe assembly will be.driven to acertain extent positively and rearwardly upon the chassis.The angle enclosed by the supporting frame and the said auxiliary rods34 increases during this procedure, until it-takes up the position asshown in Fig. 7, which will probably represent the position in which thepipe assembly has been sufficiently pushed back on the chassis, so thatthe centre of gravity of the said pipeassembly at least approximatelycoincides with that of the chassis. It will be understood that when thepipe assembly is again to be brought into working position, the spindlesare to be turned in the opposite direction so that the supporting frame4 is again erected, the latter will exert a pulling action upon theadditionaLrods 34, by means of which action the pipe assembly will againto a certain extent positively be drawn forward until the supportingframe has taken up its vertical or working position, whereupon the pipeassembly with the rods 34 is drawn through the supporting frameforwardly, until it again occupies the position shown in Fig. 6,whereupon all that remains to be done is to connect the forks shapedother possibility of attaining the desired effect.

In this case, when the pipe assembly is to be retracted upon thechassis, the spindles 6 with the nuts members I9 are lifted out of theholders I4 and folded down forwardly. Now, when the pipe assembly ispushed through rearwardly pressure is exerted via the draw bararticulated at the front end of the pipe section I upon the supportingframe 4 which is pivotably mounted on the chassis by means of thetrunnions H, in such a way that the supporting frame folds downrearwardly. If may be advisable to effect this foldmg down of thesupporting frame beforehand, for which purpose the ring whichestablishes connection between the front end of the pipe section I andthe rod 5 is first pushed rearwardly along the said pipe section. Forthis purpose grooves 31 may for example be provided on both sides at thecentre portion of the said pipe section in which the said ring meshes bymeans of a pin, being in this way guided in these grooves during thelongitudinal rearward movement. In this way the ring 36 can first bepushed back along the pipe section I so that the rod 5 which remainsconnected thereto will cause the supporting frame 4 to be folded back,whereupon the pipe assembly can be pushed rearwardly upon the chassisthrough the passage provided in the counterweight superstructure 33, thering 36 meantime proceeding in the forward direction in the grooves 31in the pipe section I until it reaches the front end thereof in theposition shown in Fig. 8.

The guiding of the cables or ropes is efiected in the following manner.

At the upper end of the supporting frame 4 the guy ropes I aredetachably hooked, and are then passed over the pulleys 38 provided atthe front position against the force exerted upon it in the forwarddirection by means of a chain 39 attached to its rear end and passedthrough the interior of the pipes 2 and I to the rear and then passedover a drum or chain wheel I0 located at the rear of pipe I and over aloose pulley 40,

being finally attached to the rear end of pipe section I. of this loosepulley 40, and is connected to the rear end of the pipe 2 via a pulley42 mounted on the front end the pipe section I, so that the said pipe 2is pushed forward so as to equalize the force exerted by the guy rope Iin the opposite direction. A turn-buckle 43 is inserted in the chain 39preferably closely in front of its point of attachment to the pipesection I, and this turn-buckle affords the possibility of eithershortening or lengthening this guy rope as required.

As shown in Fig. 13, the two chain wheels ID are mounted horizontallyand provided each with a helicoidal wheel 44 mounted upon the sameshaft. At right angles to the axis of the telescopic pipe and meshingwith the wormwheels 44 there is mounted a worm shaft 45, provided withright and left hand Worms for the two helicoidal wheels,

A further rope M is joined to the pin so that when the crank 46 isrotated both chain wheels II) can be rotated simultaneously. Thus whenrotating in one direction the pipe section 3 is drawn rearwardly by thechain 39 taking all intermediate parts with it. Owing to the tacklelikeaction of the loose pulley 40 the transmission thus effected results inthe pipe 2 being moved rearwardly at half the speed of the pipe section3, the said transmission at the same time producing a correspondingpower transmission ratio.

The hosepipes 25 which are attached to the foremost pipe section 3 atthe rear end thereof, are pushed out rearwardly through the open endduring this rearward movement.

If the crank 46 is turned in the opposite direction the loose pulley 40with the tackle-like action and with it also the rope 4I will be drawnrearwardly so that the pipe 2 will be moved forward. This positivethrust action causes pressure to be exerted upon the rope 7 via thepulley 38, so that also the foremost pipe section 3 is drawn forward.Also during the extension the,

motion of the pipe section 3 is twice as rapid as that of the pipesection 2.

If as shown in Fig. 11 more than three pipe sections are used, a pipesection 41 being for example interposed between the sections 2 and .3,all that is required to ensure positive guiding of all pipe sections isto take a rope 43 and attach it to the front end of the pipe section Iand via a pulley 49 arranged at the front end of the pipe section 41,connect said rope 48 to th rear end of the foremost pipe section 3. Aseach pipe section is to move at twice the speed of its immediatelyadjacent external neighbour, it is necessary where a pipe section suchas 41 and, if desired other pipe sections have been interposed, toprovide further loose pulleys with tackle-like action in order to obtainthis effect. In the example shown in Fig. 11 the rope H has for thispurpose been attached not direct to the loose pulley 40 but to aninterposed loose pulley 50, and the rope 5| passing over the said pulley50 is attached to the aforesaid pulley 40, whilst the other end of thesaid rope 5|, preferably having interposed therein a turn-buckle 52, isattached to the first pipe section I towards the rear end thereof. Inthis case it is preferable to arrange all the aforesaid rope guides intwo groups, for instance symmetrically on both sides of the pipeassembly.

The pipes may have any desired circular section, but they can also besomewhat flattened as shown in Figure 10, or again they may consist ofiron sections which mutually guide one another as in Figure 12. Theforemost pipe section which usually consists of one single length ofpipe to which the nozzle is attached can alternatively consist of two ormore separate pipes arranged in a bundle i. e. parallel to one another,each being provided with its own feed hosepipe, the said separate pipesbeing preferably connected in pairs by means of webs as shown in sectionon the drawings. These pipes can then have a common nozzle or each itsown nozzle, the said nozles having, if desired, differing lengths.
